In social models, chemistry set model, “reaction set model” or “molecular reaction set model”, refers to the use of a basic chemist set to explain and model human social interactions, reactions, and bond formations and changes.

Overview
In 1796 to 1809, German polyintellect Johann Goethe pioneered the logic that humans could be modeled or conceived as large evolved or metamorphosized chemicals and that their interactions, bondings, debondings, reactions, moralities, etc., can be explained by the physical chemistry “symbols” of Swedish chemist Torbern Bergman’s 1775 A Dissertation on Elective Attractions, specifically his reaction signs and symbols, affinity table, and reaction diagrams. This, historically, has been referred to as Goethe's human chemical theory or the "social retort" model, among other variants; the gist of which is captured in Goethe's affinity table.

In 1993, French sociophysicist Paris Arnopoulos outlined the gist of the transition from the billiard ball model, which is similar to the "cannon ball model" (or social cannon ball model), to the "chemistry set model", as he calls it, wherein chemical thermodynamics come into play, as follows: [3]

“When we move from the [socio-] mechanical to the [socio-] thermal phenomena of energy, we rise from the atomic ‘billiard ball’ interaction to the molecular ‘chemistry set’ reactions. Unlike the former, the latter do not consider relations simply on the basis of mass, distance, and velocity, but rather temperature, pressure, and volume. The importance of a particular position is therefore, replaced by that of a substantive composition. The physical motion of bodies is replaced by the chemical reactions of compounds [sociomasses].”
